Base64 guide

Base64 is a text encoding format used to convert binary or plain text into ASCII-safe output.

Where Base64 appears

• Tokens
• Data URLs
• Email payloads
• Embedded assets

Encode vs decode

Encoding turns text into Base64. Decoding restores the readable content.

Important note

Base64 is not encryption. It is only an encoding layer.

Final takeaway

A Base64 encoder and decoder is helpful when you inspect payloads, files, or transport-safe content.
